A temporary amnesiac state of mind endured by someone caused by the following scenario (or similar):

After one has been studying or researching intensively for a long period of time, he/she comes across a piece of complex information which warps him/her into a "mindfuck". The attempt of comprehending this mind-tangling data acts as the ignition point of an epic-scale memory implosion of the individual, thus, in simple terms, wiping out from short term memory anything the individual studied or learned in that long period of intensive study/research.

After a month of studying like an absolute fucking maniac for his exams, Edmund stumbles across Einstein's lost and unpublished answers to the Universe.
